Communications Server 2007 is the center of Microsoft’s solution for unified communications solutions. Shown here are the major Microsoft components in such a solution. Users employ the Communicator 2007 application on client PCs for instant messaging (IM), presence, and voice or video calls. The separate Live Meeting 2007 client supports Web conferences, which can incorporate voice and video as well as other media, such as text chat and application sharing.

Communications Server has several roles:

Register and track the addresses of users and their PCs
Log and control communications sessions (e.g., place and end voice calls)
Publish user presence information
Distribute audio, video, and other media for multiparty communications sessions (such as voice conference calls)
Host Web conferences including shared conference content, such as PowerPoint presentations
Enable connection by clients other than Communicator and Live Meeting, including Communicator-compatible
